second=a[1];
}
else
{
max=a[1];
second=a[0];
}
for( i=2;i<n;i++)
{
if(a[i]>=max)
{
second=max;
max=a[i];
}
else
if(a[i]>second)
second=a[i];
}
System.out.println("the second smallest nubmer is"+second);
int max=0,second=0;
if(a[0]>a[1])

max=a[0];
second=a[1];
}

{
max=a[1];

I would suggest to sort the array first and then it is simple just reguest number on second possition. Also keep in mind that you may have first two number of same value so the second smallest should be on 3rd position(but that is just extra feature of your program)

Your instructor could also be extra devious and give you an array where all the indecies hold the same value. In which case the second smallest number would still be that value

try this code.i have change few thing in u r code
int min=0,second=0;
if(a[0]<a[1])
{
min=a[0];
second=a[1];
}
else
{
min=a[1];
second=a[0];
}
for(int i=2;i<9;i++)
{
if(a[i]<=min)
{
second=min;
min=a[i];
}
else
{
if(a[i]<second)
second=a[i];
}
}
System.out.println("the second smallest nubmer is "+second);
int min=0,second=0;
if(a[0]<a[1])
{
min=a[0];
second=a[1];
}
else
{
min=a[1];
second=a[0];
}
for(int i=2;i<9;i++)
{
if(a[i]<=min)
{
second=min;
min=a[i];
}
else
{
if(a[i]<second)
second=a[i];
}
}
System.out.println("the second smallest nubmer is "+second);

Already I can see problem here, in both cases if/else statement will be useless if first two numbers will be some of largest. You are expecting smallest number to be on one of first two positions in array.
Consider following array and think about it again

arr = {4, 5, 1, 3, 2} Last edited by peter_budo; Apr 8th, 2007 at 4:36 am.
